Senior Retail Media Manager

Senior Manager, Retail Media About the Role Jellyfish is seeking a Senior Manager, Retail Media to lead campaign strategy, activation, and performance across multiple retail media networks for a major, high-visibility household brand. This is a hands-on, client-facing role at the center of an account we are actively investing in and elevating. You will own a multi-retailer portfolio spanning Walmart Connect, Target Roundel, Criteo, and Home Depot's Orange Apron Media. We are looking for someone fluent in self-service retail media platforms who can build and defend a point of view with clients, and who treats budget governance and operational rigor as core to the craft rather than an afterthought. This is a senior seat with real autonomy. You will receive clear scope, priorities, and senior-level direction, and from there you will run your platforms end to end and lead the team supporting them, anticipating what the client and account leadership need and bringing solutions alongside the issues you raise. What You Will Own - Multi-retailer platform ownership. Serve as primary platform owner across Walmart Connect (search and display), Target Roundel, and Criteo for Lowe’s, Costco, and Best Buy. Own campaign architecture and structure, keyword and targeting strategy, bid strategy, budget pacing, cross-retailer allocation, performance analysis, and tentpole planning through Deals Week, Circle Week, and holiday. - Cross-retailer insight. Translate retailer-specific results into a coherent portfolio narrative: portfolio-level budget recommendations, incrementality perspective, and category and competitive context. - Client leadership. Own the full operating rhythm for your platforms, not just campaign execution. Set agendas, present performance and recommendations directly to client stakeholders in weekly and monthly forums, flag risk early, and follow through on every commitment. - Budget governance. Own pacing, spend caps, flight dating, and billing reconciliation for your platforms. Identify and escalate discrepancies such as misbilled activity, platform outages, and attribution gaps, and lead make-good and credit conversations with retailer partners. - Retailer partnerships. Build durable relationships with Walmart Connect, Roundel, and Criteo partner teams to unlock betas, secure support, and resolve issues quickly. - Team leadership. Manage and develop the Associates and Senior Associates supporting your platforms. Set their priorities, review and quality-check their work, coach on platform craft and client communication, and give the regular feedback that moves them forward. - Process and team leverage. Document campaign structures, naming conventions, QA checklists, and optimization cadences so the account runs on process rather than tribal knowledge. Set the standard your team and our offshore execution partners work to, and hold the quality bar across everything that ships. - Planning and strategy. Contribute to annual and quarterly planning, new product launch support plans, and test-and-learn roadmaps in partnership with account leadership. What You Bring - 5+ years in retail media or commerce media, with hands-on, in-platform ownership of self-service retail media networks. - Demonstrated depth in Walmart Connect and/or Target Roundel (TPA / self-service). Criteo self-service is a strong complement. Experience across two or more of these is a significant advantage. - Broader retail media experience across networks such as Amazon Ads, Instacart, Kroger Precision Marketing, CitrusAd, or Home Depot's Orange Apron Media is welcome and valued. - Strong command of budget management fundamentals: pacing, caps, flighting, invoice reconciliation, and spend or billing discrepancy resolution. - Demonstrated experience owning client-facing communication: leading performance readouts, defending recommendations, and managing expectations under scrutiny. - A genuine understanding of what client and campaign management actually are: o…
